Launching The Android SDK Emulator

1)     To launch the emulator, also known as the Android Virtual Machine, you can follow any of the two steps. Either you click the AVD button in you menu strip or click the Window tab and from there click the Android Virtual Device. In both the cases, a same new window would appear.

4) A new window will appear showing that you have successfully made a virtual device, now start up this device by clicking the start button on the right hand side.


5) When it’s done loading, a virtual device will appear like this one:


6) The virtual device is an emulated screen of Android Smartphones to test and debug your apps. Depending on the speed of you system, it may take some time to change to an android screen.

I am using core i3 processor, but if you are on a Dual Core or Core 2 duo system then you must have some patience.

Finally you can see this screen as we selected Google Nexus S, operating system API 16.


7) That’s just not it, it’s just a portrait view, but if you wish to change the screen to landscape view, press (Ctrl + F11).
